4num;ovuMEN'r IN MATCH- suck The 'Schedule referred to in these Letters Pa'texlfand. mallgirxg part of the name VBe it known that I, J OHN K. ROBINSON, of Middlebnry, iu the county of Summit and State of' Ohio, haveinvented certain newr and useful 'Improvements in Match-Stick, of which the following is a specification.

Description of Drawing.

Figure 1 is aside view cfa block of matches.

Figure2, a view of the topor ends of the matches.

Figure 3, a detached match.

Like letters of reference refer to like parts i-n the different views.

"Nature and Qbject of the Invention. v

This invention relates to the construction of matchsticks V so that saidV matches shall have thin edges whereby-.they more readily ignite, as hereinafter more fully set forth.

Gen-eral Description.

Matches are usuallymade both round and square, the square ones being split from blocks of wood, and the round ones made by passing the material through dies, whereby they are rounded.

i The objectipn to the shape of the square and round match is that, in consequence of their round and rectangular form,they do not always ignite ou firing the fulminate, and more especially is this the case when the wcod is not coated with sulphur. The squareness and roundness of the wood offer no salient points or thinness `of' material that will readily burn; hence, if-

they'are not largely supplied with i'ulminate, the wood does not ignite, aud thus results 'a waste of matches and delay in obtaining alight.

To avoid this waste of matches, I make them of the shape shown in fig. 2, which is that of a lozenge or rhomhus, thereby obtaining to the match two .thin edges, A B, formed by the acute angle of the figure.

'By thus giving to the match two thin feather-like edges it Iwill readily ignite on riug the fulmiuate, so

that no loss will ensue in consequence of the wood not taking fire.

n; The matches are made from splitting them from 'blocks of wood, and the shape obtainedby the direc# tion given tothe cleverage, and which is shown inthe` surface of a block, fig. 2.

v i i Claim. Y

What I claim as myimprovemeut, und desire to secure 'by Letters Patent, is-

A match-stick, the shape of which, transversely, is that of adozenge or rhombus, as and for the purpose specified.
